Tayam, Luminous Enigma + Sengir, the Dark Baron + Ashnod's Altar + Strangleroot Geist

Tayam, Luminous Enigma

Sengir, the Dark Baron

Ashnod's Altar

Strangleroot Geist

How it works

1. Activate Ashnod's Altar by sacrificing Strangleroot Geist, adding CC.
2. When Strangleroot Geist dies, its undying ability and Sengir's first ability trigger.
3. Resolve the Strangleroot Geist trigger, returning it from your graveyard to the battlefield with a +1/+1 counter and a vigilance counter on it.
4. Resolve the Sengir trigger, putting two +1/+1 counters on Sengir.
5. Activate Tayam by paying 3, removing a +1/+1 counter from Sengir, and both counters from Strangleroot Geist.
6. Holding priority, activate Ashnod's Altar by sacrificing Strangleroot Geist, adding CC.
7. Repeat steps 2-4 one additional time.
8. Activate Ashnod's Altar by sacrificing Strangleroot Geist, adding CC.
9. Resolve Tayam's ability from step 5, causing you to mill three cards and returning Strangleroot Geist from your graveyard to the battlefield.
10. Repeat.

This elegant loop transforms the constant cycle of life and death into an engine for infinite value, anchored by Strangleroot Geist trading places between the battlefield and the graveyard. Ashnod's Altar fuels your spellwork and provides the initial sacrifice outlet, while Sengir, the Dark Baron grows exponentially larger with every fallen creature by collecting two +1/+1 counters each time. Meanwhile, Tayam, Luminous Enigma serves as the mastermind of the operation, using the counters supplied by Sengir and the Geist to continuously recur permanents of mana value 3 or less while milling your library.
